Аннотация

An approach is presented for incorporating metadata constraints into queries to be processed by a distributed environmental information system. The approach, based on novel metamodel unifying concepts from the Unified Modelling Language (UML), the Object Query Language (OQL), and the Resource Description Framework (RDF), allows metadata information to be represented and processed in combination with regular data queries.
